At present, there are more than 10 second-level transaction platforms for securities tokens around the world, but the entire trading market is still immature and the liquidity needs to be improved. When selecting a distribution platform, it provides technical security, distribution costs (the fee charged by the Platform), and third-party service providers (such as brokers and lawyers) that cooperate with the platform) whether the issuer has experience and advantages in the industry and region, w

previous article, one of the little details we skipped was mining rewards. Now, we are ready to refine this detail. Mining rewards, in fact, is a coinbase transaction. When a mining node starts digging a new block, it pulls the deal out of the queue and appends a Coinbase transaction to the front. The Coinbase transaction has only one output, which contains the

Block hashing algorithmBitcoin Mining uses thehashcashproof of work function; The Hashcash algorithm requires the following PARAMETERS:A service string, a nonce, and a counter. In bitcoin the service string was encoded in the block header data structure, and includes a version field, the hash of the Previous block, the root hash of the Merkle tree of all transactions in the block, the current time, and the difficulty. Bitcoin stores the nonce in the Extranonce field which are part of the

transaction input has the right to use the output from the previous transaction check that the transaction signature is correct As shown in the figure, the process of signing and verifying the data is as follows: Now to review the complete lifecycle of a transaction: At first, the Genesis block contained a Coinbase transaction. In Coinbase transactions, there is no input, so there is no need to sign. The

size is limited to 1MB (a new virtual currency, called Bitcoin cash--bcc, which is currently 8MB), was just born a few days ago. Because the size of the block is limited, the number of transactions that can be accommodated in each block is limited. The current Bitcoin system provides an average of 10 minutes per block, so the way miners work is essentially collecting all the transactions generated online within 10 minutes and then filling in a block. This block is approximately as shown in the
